# Convert date to Age

D

#### D G

I need to convert a date of birth to age. However, I need to base it
on Sept 1, 2011. I need to know how old (years only) that person is
on that date. Does anyone know how to do this. Why is September 1,
2011 so important. It allows me to determine if they are eligible(too
young or too old) to play a sport.

date of birth in A1, Sept 1, 2011 in B1 then:
=DATEDIF(A1,B1,"Y")

enter this in C1
=(\$B\$1-A1)/365.25

B1 is 1-9-11
A1 is date of birth
change format in column C to number with 1 decimal place.

Roger Dodger,
If you change the resulting cell to two (2) decimal places, in the cell
format, it would be better. Or better yet, use the "rundown function such
as:
" =rounddown((\$B\$1-A1)/365.25,0) " (w/o quotes) .

Place minimum age in Cell C1 and using:
" =If(rounddown((\$B\$1-A1)/365.25,0)<\$C\$1."InEligible",Eligible) " (w/o
quotes) .
